Finally, an interesting and short explanation of the principle. Short but efficient as it include everything needed. I looked for 30 mn on youtube through very long and not informative videos with millions of views before to find this one. Unfortunately, the best videos on you tube are often the ones with not a lot of views. Anyway, thank you for this good video.
Conventional / DC current : Current is flow of electrons, but "current" and electrons flow in the opposite direction. CURRENT flows from positive to negative and ELECTRONS flow from negative to positive...as illustrated in this video. When referring to "current" it is assumed you're referring it flowing from POSITIVE TO NEGATIVE. The flow of electrons is termed electron current. Electrons flow from the negative terminal to the positive. Conventional current or simply current, behaves as if positive charge carriers cause current flow. Conventional current flows from the positive terminal to the negative. Perhaps the clearest way to think about this is to pretend as if movement of positive charge carriers constituted current flow INSIDE a car battery, the ELECTRONS flow (as stated prior) from negative to positive....creating the power in a battery essentially.....outside of same battery at terminals the CURRENT flows from POSITIVE TO NEGATIVE throughout the various components in automobile. Feel free to chime in if you feel I stated anything in error.
If this were an AC circuit, your comment would be correct. This is a DC circuit, and based on what the circuit is doing, the side of the DC source the switch is on would be irrelevant.

@@gnidnoeled786 Electrons are negatively charged and flow from the negative terminal to the positive. However when electricity was first discovered Scientists guessed incorrectly that the electrons were going from positive to negative. So coventionally we say the current is going from positive to negative whilst in reality the opposite is true. Very confusing!
